The insertion of "only" between "beginning" and "of" makes the sentence confusing and awkward. The sentence is attempting to say that the flood began a sequence of awful natural disasters, but "only" should be moved to better indicate this. The answer choice that best clarifies the sentence is "The flood was only the beginning of the area's experience."

In the sentence as it is written, "only" is floating between phrases, and it is not clear what exactly the word is modifying. The sentence is trying to say that the king was the singular person with the ability to exercise the power. So, "only" should be placed next to "person" to make this clear. The only answer choice that places "only" before "person" is "The king was the only person in the country who could exercise such power."

The use of "just" at the beginning of the sentence is awkward and confusing, making it unclear what exactly the adjective is modifying. The word makes the most sense if it modifies "seventeen," to emphasize the subject's youth during his "first arrest." "He was just seventeen when he first got arrested" is the answer choice that best makes use of the word "just" by placing it directly before "seventeen."

The placement of "only" in the sentence is confusing and odd, as it seems to imply that the subject was merely the driver who finished. The sentence will make the most sense if "only" is used to show that the winner was the one driver to finish. The sentence which best does this is "The race's winner was actually the only driver to complete the full race."

The use of "only" in the sentence is confusing, and makes it unclear what is being modified by the adjective. The word can be better used by placing it at the front of the underlined phrase to show the subject was the third person from the country; therefore, the correct answer choice is "only the third person from his home country."

In the original sentence, the boy is the subject of the sentence, so the phrase "with its teeth bared" would be a modifier for him. The author was intending to use this phrase to describe the wolf, so one has to choose an option in which the phrase clearly modifies the wolf. In "With its teeth bared, the wolf approached...," the wolf is the subject of the sentence, so the modifier applies correctly. 

The sentence, "With bared teeth the boy cowered as the wolf the sheep approached" does not fix the modifier, and it is confusing to read without a comma setting off the prepositional phrase, "with bared teeth." The sentence, "Its teeth was bared as the wolf approached the sheep and the boy was cowering as it did so," is needlessly wordy. The sentence, "With his teeth bared, the boy cowered as the wolf approached the sheep" still has a misplaced modifier, and now that "his" is added, it is significantly more confusing.

The original statement is grammatically incorrect because "audience" and "show" should be plural.  Also, "his audience enjoying the show" makes the sentence into a run-on.  The correct answer is concise and not awkward.  

The sentence as written is actually a fragment, as it does not contain a proper verb. The word "appreciating" in the sentence is a gerund, or a verb form that can function as anoun. The correct answer will use a full verb form, as "Every person in the room appreciated the jokes by the performers" does.

The underlined phrase in the sentence is awkwardly worded, which makes the sentence itself difficult to understand. The "religious texts" contain contradictions, a meaning not conveyed properly by the sentence. "Contradicting themselves" is the clearest, most appropriate choice among the answers.

The underlined phrase is very awkwardly worded, and the use of the past perfect form "have been" is confusing. The phrase needs to be cleaned up for better clarity of meaning. "When they are adults" is the best choice among the answers.
